How would doubling the mass of Earth affect the gravity we experience?​

Physics

N76 [4]3 years ago
5 0
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.

He pictures show a grassy field that has been abandoned. Which best explains why this is an example of increasing entropy?
solmaris [256]
<h2>Answer:</h2>

The correct answer is option D. Which is "Over time, the lawn has naturally become disorderly".

<h3>Explanation:</h3>
  • Entropy, the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work.
  • It is also a measure of the molecular disorder, or randomness, of a system.
  • According to above definitions of entropy option D is correct.
  • <u>So entropy of system is randomness/disorder that is increasing with time in case of lawn.</u>

In a young's double-slit experiment, the angle that locates the second dark fringe on either side of the central bright fringe i
dem82 [27]

Answer:

(d/λ) = 17.67

Explanation:

Equation for double-slit:

d*sinθ = m*λ

Rearrange the equation

(d/λ) = m/(sinθ)

Since it is at the second dark fringe, m = 2

Therefore:

(d/λ) = 2/(sin(6.5)

(d/λ) = 17.67

An olympic high diver has gravitational potential energy because of her height. as she dives, what becomes of her energy just be
sammy [17]

An Olympic high diver has gravitational potential energy because of her height. As she dives, kinetic energy becomes of her energy just before she hits the water.

Gravitational potential energy is the energy possessed or acquired by an object due to a change in its position when it is present in a gravitational field. In simple terms, it can be said that gravitational potential energy is an energy that is related to gravitational force or to gravity.

Kinetic energy is the energy of motion, observable as the movement of an object, particle, or set of particles.

When the high diver is standing stable and not moving , that diver has a gravitational potential energy because of the height . The moment she dives , before hitting the water , from being stationary she gained some momentum and come in motion , due to motion her gravitational potential energy will change to kinetic energy before hitting the ground.

The transverse motion of a star can be determined by studying its spectrum. TRUE or FALSE
Klio2033 [76]
Nope.
False.
The shift in spectral lines reveals only 'radial' motion ...
motion toward us or away from us.  The spectrum
carries no information related to motion across the
line of sight.
